The present study is aimed towards the investigation of starting characteristic of supersonic air intake by adopting the cowl porosity. A computational study has been performed with k-omega turbulence model adopting the RANS solver. Air Intake shows the unstart phenomenon for the clean model case and this could be due to large shock wave boundary layer interaction near the throat. After implementing the cowl porosity, intake shows the starting behavior and there after a compression in the flow is observed. It also improves the quality of flow and performance of supersonic air intake. The obtained result have been validated with the previously published data. All the calculations were performed at design Mach no of 2.2 for free flow conditions.
